Power. Screw Conveyor. The calculation according to ISO 7119-1981. Applies only to conveyors. If machine working as feeder (although the design may be identical - the process of operation is different) the power of the motor should be greater due to start at full fill - more torque will be needed.

Most screw conveyor drives are considered to be 88-percent efficient due to a combination of motor and gearbox efficiencies. KWS encourages the use of high efficiency drives, but does not recommend calculating Total Horsepower with a drive efficiency greater than 93-percent because it can lead to undersized drives and components.
